6. Installation

6.1. Mounting

6.2. Antenna mounting

M!DGE Wireless Routers will only operate reliably over the cellular network if there is a
strong signal. For many applications the flexible stub antenna provided would be suitable but in
some circumstances it may be necessary to use a remote antenna with an extended cable to allow
the antenna itself to be positioned so as to provide the best possible signal reception. RACOM
can supply a range of suitable antennas.

Beware of the deflective effects caused by large metal surfaces (elevators, machine
housings, etc.), close meshed iron constructions and choose the antenna location accordingly.
Fit the antenna or connect the antenna cable to the ANT connector.

In external antennas the surge protection of coaxial connection would
be required.

Note

Be sure that the antenna was installed according to the
recommendation by the antenna producer and all parts of the antenna and
antenna holder are properly fastened.

6.3. Grounding

Grounding screw has to be properly connected with cabinet
grounding using a copper wire with minimal cross section of 4
mm2.

6.4. Power supply

M!DGE can be powered with an external power source capable of
voltages from 10 to 55 Volts DC. M!DGE should be powered using a
certified (CSA or equivalent) power supply, which must have a limited
and SELV circuit output.

M!DGE is equipped with dual power supply connector – it is
possible to use two independent power supplies (even with different
voltage). The ground terminals are connected together and they are
connected with the box grounding as well.
